Abstract
The aim of this research was to prepare and analyze suitable microcapsules for the chosen end use—that is, bow-ties. The produced microcapsules were composed of melamine formaldehyde microcapsules with fragrance oils in the core. Regarding the properties, the surface morphology (studied by Scanning electron microscopy (SEM)), thermal properties (measured by Simultaneous Thermal Analysis [STA]), size and size distribution (by SEM and ImageJ software), and release behavior of the microcapsules were analyzed. The microcapsules were further (in two trials) applied with a screen-printing technique to textile materials which were investigated by microscopy (SEM) and tested for thickness, mass per unit area, and crease recovery angle. Finally, the scented bow-ties were designed and a subjective wear test was performed by the participants. According to the results, the prepared microcapsules were undamaged, with a spherical and smooth surface. An impermeable shell enabled the fragrance to be released simply by rupturing the microcapsules. This property was desired, since a stronger release through the permeable shell could be annoying for the wearer. During wear, the fragrance faded, but by rubbing the surface of the bow-tie and consequently rupturing the microcapsules, the release of the fragrance was initiated again, before or after wear.
